HUZHOU MAILONG MACHINERY CO., LTD.
Cut the raw material according to the outer diameter of the product. Cutting the round steel to the specified length, and then put it into the forging die to forge the blank to the specified size.
The dimension and surface inspection shall be carried out after the forging is completed, and the next process shall be carried out after no problem is found in the inspection.
Using natural gas furnace, fast heating, high output, energy saving and environmental protection.
After forging, the internal structure of the material is optimized, which is equivalent to heat treatment and mechanical properties are improved.
Forging according to the size and shape of the product can save the finished product compared with the direct processing of round steel.
The raw material of steel pipe shall be cut accurately according to the length and size of the product.
After cutting, the length and size of steel pipe shall be measured and tested to ensure that there is no problem with the size. Enter into the next process after the test is correct.
High precision machine tool is used for cutting raw materials. The raw materials of steel pipes are cut directly according to the product length.
The machine has the advantages of fast cutting speed, high production efficiency and accurate size control. Moreover, direct cutting has less environmental pollution and is more environmentally friendly.
Roughing and finishing according to drawing requirements. The sprocket is processed by the whole vehicle, hole, chamfering, hobbing, grooving, punching, tapping, etc.; the roller is processed by the screw rod, roller barrel, welding, etc.
After finishing machining, the inspector shall conduct inspection and enter the next process after passing the inspection.
All of them are processed by CNC machine tools, which can effectively ensure the accuracy of products. Each process is inspected by a special inspector to ensure that the dimensions meet the drawing requirements, ensure the tolerance range and effectively control the product quality.
Different products have different surface treatment requirements. Carry out surface treatment according to product requirements. Surface treatment can increase the service life of products.
There are many kinds of surface treatment, such as quenching, carburizing, blackening, phosphating, zinc plating, rubber coating, plastic spraying and so on. Enter the next process after inspection.
According to the customer's requirements, the surface treatment of products can be carried out, and most of the surface treatment can be carried out by themselves, without processing in the outsourcing processing workshop.
This can greatly improve production efficiency. Surface treatment can enhance the service life of products, and the surface treatment of sprockets can also enhance the hardness of products.
Clean, deburring and derusting the sprocket and clean the surface of the roller. Standard export plywood case is adopted. The inside of the case is covered with oil and dust-proof plastic bags.
The sprockets are packed in separate plastic bags and then put into small cartons and then put into the plywood case. The roller is loaded into the case according to the size.
The export of plywood case does not need fumigation, and has good structural strength and high stability. It has the advantages of light material, high strength, good elasticity and toughness, shock resistance and vibration resistance, easy coating, insulation, etc. Recyclable, conducive to environmental protection.
